Investigative Drug


Published on

This presentation based on how will you present your case in front of ODAC meeting with FDA. It shows ability to find the data, guidances,designing of clinical trials, compilation, strategies to make drug readily available by its ability to meet designations like fast track, priority review,orphan drug designation etc.

    8. 8.<br /><br />Lung Cancer is the leading cancer killer in United States <br />Leading cancer killer in men and women in United States (29% of all cancer deaths)<br />219,440 new cases of lung cancer in 2009<br />159,390 deaths from lung cancer<br />5 year survival rate in patients with lung cancer is less than 15.2%<br />
    9. 9. Types of lung cancer<br />The two main types of lung cancer are:<br />Small Cell Lung Cancer (SCLC)<br />about 10% of all lung cancer patients are of these type<br />Non Small Cell Lung Cancer (NSCLC)<br />about 80-90% of all lung cancer patients are of these type<br /> Other types of tumors include Lung Carcinoid Tumors, whichare slow growing and can be cured by surgery.<br /><br />
    10. 10. Types of Non Small Cell Lung Cancer (NSCLC)<br />The 3 sub-types of NSCLC differ in size, shape, and chemical composition.<br />Adenocarcinoma: <br /> About 40% of lung cancers.<br /> Usually found in the outer part of the lung<br />Squamous cell carcinoma: <br />About 25% to 30% of all lung cancers are this kind. <br />Usually develops in the middle of the lungs, near a bronchus.<br />Large-cell (undifferentiated) carcinoma: <br />About 10% to 15% of lung cancers are this type. <br />It can develop in any part of the lung.<br /><br />

    91. 91. Hazard Ratio<br />How often a particular event happens in one group compare to how often it happens in another group, over time. In cancer clinical trials it measures survival at any point in a group of patients who have been given a specific treatment compared to a control group given another treatment or a placebo. A hazard ratio of one means that there is no difference in survival between the two groups. A hazard ratio of greater than one or less means that survival was better in one of the groups.<br /><br />
